The invention provides a half-ship floating total longitudinal strength evaluation method, which comprises the following steps: firstly, selecting a section with the maximum ship body bending moment as an evaluation calculation section according to floating stowage, and obtaining the section bending moment and the section shearing force of the evaluation calculation section, the evaluation calculation section comprising a deck section and a ship bottom shell plate section; then profile characteristics of the evaluation calculation profile are obtained, total longitudinal bending stress and total longitudinal shearing stress are obtained, and the total longitudinal bending stress comprises the total longitudinal stress at the deck and the total longitudinal stress at the hull bottom outer plate; and calculating the total longitudinal bending stress balance and the total longitudinal shearing stress balance according to the total longitudinal strength evaluation balance of the whole ship design. And finally, evaluating the result, comparing the total longitudinal stress and total longitudinal bending stress at the deck, the total longitudinal stress and total longitudinal bending stress at the ship bottom outer plate, and the total longitudinal shearing stress and total longitudinal shearing stress, so as to judge the safety of the ship structure. The total longitudinal strength of half-ship floating is evaluated when the ship is in a state that the ship is not completely built.
本发明提供一种半船起浮总纵强度评估方法,首先根据起浮配载选取船体弯矩最大的剖面作为评估计算剖面,并获得评估计算剖面的剖面弯矩和剖面剪力,评估计算剖面包括甲板处剖面和船底外板处剖面。然后获得评估计算剖面的剖面特性,获得总纵弯曲应力和总纵剪切应力,总纵弯曲应力包括甲板处总纵应力、船底外板处总纵应力。根据整船设计的总纵强度评估衡准计算总纵弯曲应力衡准及总纵剪切应力衡准。最后评估结果,比较甲板处总纵应力与总纵弯曲应力衡准、船底外板处总纵应力与总纵弯曲应力衡准以及总纵剪切应力与总纵剪切应力衡准,以判断船舶结构的安全性。实现在船只处于尚未完全建造完成的状态时进行半船起浮总纵强度评估。
